But the Canberra Liberals have raised questions about the push for a pay freeze just days after lobbying for more politicians.

"I think it's ironic that Katy Gallagher is trying to make some noise about this the day after she's put forward a proposal for doubling the number politicians in the assembly," Mr Hanson said.

"So 35 MLAs, over the forward estimates I calculate that would cost about $65 million.

"So on the one hand she's sort of proposing let's have more politicians, spending tens of millions of dollars of taxpayers money and then she's really scratching around in the dirt to try to say let's take a pay freeze for a year. "
